Morphology

ultrasonic + flaw + detector

The compound is directly compositional: 'ultrasonic' (high-frequency sound) modifies 'flaw detector' (a device that finds imperfections), so the meaning 'a device that uses ultrasonic waves to detect flaws' is transparently derivable from its parts. Although somewhat technical, the adjective+noun naming pattern is regular and cross-linguistically common, so a B1 learner who knows the constituent words would readily infer the meaning.

Etymology

Ultrasonic flaw detector gets its name from two simple parts: ultrasonic means sound too high for our ears, and a flaw detector is a tool that finds faults. Like a bat sending high sounds and listening for echoes, the device sends ultrasonic waves into a material and listens for changes, so it can find 'hidden cracks' inside.
